Abstract

The invention discloses a two-motor coordination control device for improving the stability of a whole vehicle. The two-motor coordination control device for improving the stability of the whole vehicle comprises a left speed sensor, an electronic control unit, a right speed sensor, a two-motor coordination controller, a left motor controller, a right motor controller, a left wheel hub motor, a left servo controller, a right servo controller, a right wheel hub motor, a left wheel, and a right wheel. The two-motor coordination control device for improving the stability of the whole vehicle can improve the stability of the whole electric vehicle and guarantee the steering effect, and is convenient to operate.

Description

technical field [0001] The invention relates to a two-motor coordination control device for improving the stability of a whole vehicle, which belongs to the technical field of automobiles. Background technique [0002] Along with the rapid development of the automobile industry, the environment has also been greatly damaged. In recent years, the smog phenomenon in our country has been terrible, so people began to urgently need to find a suitable energy source to replace fossil energy sources. Electric vehicles have the advantages of low emission, low noise, and simple structure. People gradually shift the research focus to the field of electric vehicles. However, electric vehicles driven independently by in-wheel motors cannot use mechanical differentials, which will lead to a decrease in the stability of the vehicle, poor steering effect, and insufficient safety. [0003] Therefore, in order to improve the stability of the electric vehicle, it is necessary to design a two-...
